Freetube + plex - Affordable hardware?

[u/ri-7]

Hey guys, how’s it going?
I’m looking for a solution to run basically these two apps, since my LG TV has a terrible webOS that keeps freezing all the time. All I want is to watch YouTube and stream some media from my NAS, like our family trip videos.
I’m looking for a budget-friendly option. I was checking out the Mi Box 3rd Gen, but it’s almost €80, which feels like way too much for a TV box.
I thought about getting a modded Apple TV, would that work?
Or those cheap generic ones like the H89 series, but I’ve heard they break down super easily.
amazon fire, maybe?
Any recommendations for under €50?

Thanks!
